[Growth dyssymmetry of Shigella flexneri 6(762 S) cells].
Dyssymmetry in the growth of the initial and secondary shigella cells at early stages of the formation of microcolonies has been revealed by the method of dynamic morphometry in serial photographs obtained by time-lapse microfilming. Electron-microscopic autoradiography has allowed revealing dyssymmetry in the assimilation of exogenous H3-thymidine, H3-threonine, H3-asparaginic acid by different halves of shigella cells in the process of their growth and preparation for mytosis. These results suggest that the shigellae are divided into two unequal cells: the "mother" cell and the "daughter" one.
